I recently upgraded my late-2007 MacBook by installing a larger hard disk and upgrading to Snow Leopard. I downloaded Apple’s latest developer tools, all 3.5 gigs of them, and set the installer aside in a directory of other software I wanted to install. When I ran the install package, things went fine until I got to the part where it would actually start copying the files. Then the installer quit with a slightly mysterious error message (“can’t find the information needed to install,” or something to that effect). I noted that there was no /Developer directory on my disk and created one, but that didn’t help.

It turns out that the downloaded disk image containing the installer has to be mounted for the installer to run properly – once I ran it out of the mounted image, I had the pleasure of agreeing to a separate license for the iOS SDK as well as the one for the OS X SDK and tools. I can’t imagine why this is. But it’s installed now (and seems to run OK).
